CLEWS – Climate, Land-use, Energy and Water Systems CLEWS

The Climate, Land-use, Energy and Water Systems (CLEWS) models are focused on assessing interlinkages between resource systems in order to understand how production and use of food, energy and water security resources may contribute to climate change, and how climate change may affect resource systems. The models also assess where

The Climate, Land-use, Energy and Water Systems (CLEWS) models are focused on assessing interlinkages between resource systems in order to understand how production and use of food, energy and water security resources may contribute to climate change, and how climate change may affect resource systems. The models also assess where pressure points exist and how to minimise trade-offs. This type of framework for integrated resource assessments involves a strong quantification process which requires the development of sectoral models (for water, energy and land use), taking in consideration different climate futures.
By comparing different technologies and value chains, the model can identify pressure points, and indicate synergies and trade-offs to reach development goals. CLEWS can analyse policy decisions on issues such as the promotion of clean energy, competition for water and agricultural modernization.

Within the DIAMOND Project, the development of a CLEWs-EU model is planned.
